' The thrust block-may7 if desired', be abab- My invention relates to roller bearing journal boxes. While roller bearing journal boxes to some extent have been utilized for railroad cars, the high cost of the boxes has ma-de their application on a substantial commercial scale practically prohibitive from the point of cost. to a ,substantial elimination of the machine work now required in the making of such boxes, and to a simplification of the parts which greatly reduces the cost thereof and provides a much more durable and effective structure. My invention also comprises various features which I shall hereinafter describe and claim.

In the accompanying drawings Fig. l is a vertical section of a roller bearing journal box embodying my invention. Fig. 2 is a horizontal section on lines II-II of Fig. 1, and Fig. 3 is an end elevation of the box half in section.

Referring more specifically to the drawings, 2 indicates the journal box or housing having therein roller bearings 3 mounted be tween the race l carried by the journal 5, and the race 6 rigid with the housing 2. The bearings 3 are held in position by means of the annular spacer which is held from turning with the roller bearings by means of the projecting portion 8 which extends into the recess 9 which may be cast in the inner face,

of the housing closure 10. Both the projection 8 and recess 9 are preferably of rectangular shape.

The thrust block 1l, which engages the end of the journal and holds the housing in preper relation thereto, seats in a central aperture l2 in the spacer 7 which is preferably tapered.

To compensate for wear of the thrust block, shims 13 may be inserted between the thrust block ll and the closure l0. The closure l0 is secured to the box by the bolts l5.

It will thus be seen that the various surfaces of my device7 such as the edges 14 of the housing engaged by the closure 10 and the inner face of the closure, may be brought to bearing by the usual grinding operation and th at special machining is not required in any of the parts.

My invention is directedv bitt die casting. A

The terms and expressions which I have employed are usedl as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, ofrexcluding any mechanical equivalents of the features shown and described, or portions thereof, but recognizel that various structural moclications are possible within the scope of the inventionsclai'med.

What I claim is V j l. `In a journal box'having roller bearings arranged between thejournal and the housing; a spacing member adjacentthe ends of theroller'bearings to hold them in operative position; an angled projection on the spacer; a closure for the box having a recess in which Vthe projection seats `adapted 'to hold' the spacer against rotation the'inner face ofthe closure being flat and terminating at the entrance to the box; and a thrust block seated inA an 4opening in the spacer and hel din operai tive relation to the journal by theclosure member. I l v 2. In a journal box having roller bearings arranged between'the journal and the hous-v ing; a spacing member adjacent the ends ofv the roller bearings to hold them in operative position; a rectangular projection on the spacer; a closure for the box having' a rectangular recess in which theprojection seats to; hold the spaceragainst rotation; and a thrust block seated in an opening in the spacer and heldin operative relation to the journal by the closure member. j p f v 3. In a journal boxhaving roller bearings arranged between the journal and the housing; a. spacing member adjacent the endsof the roller bearings to hold 4them in operative position; a projection on the spacer; a closure for the box having an inner face adapted to be `brought to a flat bearing over substantially Y its whole area by a grinding tool,and having also a recess therein for thesaid projection adapted to hold the spacer against rotation;

and a4 thrust block seating in 4an opening in the spacer and heldin operative relation to the journal by the closure member.

4; In ajournal'box having roller bearings se Y arranged between the ournal and the housl Aclosure serving to hold ing; a spacing member adjacentthe ends oi the roller bearings to hold them in operative position; a closure for the box interlocking with the spacer to hold it against rotation;

said V.closure having a flat inner face terminating at the entrance to the box whereby said tace is adapted to be brought to a latbearing with the housing by a straight grinding operation, said spacer having an outwardly flared rectangular opening, and a thrust block in said opening held from inward movement. by said flared opening and held from outward movement by the closure member.

5. In a journal box having roller bearings arranged between the journal and the housing, a closure for the housing, a spacing member separable from said closure and cooperating between said closure. and bearings tohold the latter in operative position, said member having a flared opening therethroughfand a opening in the spacer and held in operative position therein by the closure member. Y

9. `In aj ournal box having roller bearings arranged between the journal and the housits inner vertical face for receiving portions Y of thel spacer to hold the same against rotation, and a thrust block seated in the spacer and held in operative relation to the journal by the closure. l
